ABSTRACT:
A prescan system, and a reproducing apparatus having such a prescan system, which performs a prescan of a recording medium to determine whether auxiliary information (such as audio signal information, character information, code information or the like) is recorded thereon in association with video information. If such auxiliary information is present, the prescan is completed to permit appropriate read-out or other use of the auxiliary information. If no such information is detected, the prescan is terminated, to reduce unnecessary loss of time. Even if such auxiliary information is present, the prescan can be terminated by an instruction from an operator.
